SIM Card and Internet in Madagascar: Staying Connected on the RN7 and the Tracks

A Madagascar road trip alternates a patched ribbon of tarmac on the RN7 (Antananarivo-Antsirabe-Fianarantsoa-Ranohira-Toliara) with long stretches of laterite track toward the west — Morondava, the Tsingy de Bemaraha, the Avenue of the Baobabs. On these sections, often without continuous signage and sometimes without a reliable paper map, an offline navigation app (Maps.me, Google Maps with downloaded maps) remains the simplest safety net for not getting lost at an unmarked fork or a river crossing.

The network also serves more urgent needs: reconfirming a lodge booking in Ranohira or Isalo, checking the last ferry time on the Tsiribihina or Manambolo rivers (they only cross in daylight), or simply letting someone know you're running late on a rough track. Most visitors travel with a local driver who knows the terrain — but that's no substitute for your own connection to reach family back home, make online payments, or handle the unexpected once the driver has gone to rest for the night.

French carriers now treat Madagascar under their more generous travel offers. Since 31 March 2026, Free has offered Free Max, the first French plan to include unlimited data abroad across 118 destinations including Madagascar, at €29.99/month (€19.99 for Freebox subscribers); its 350 Go 5G plan separately includes 35 Go usable at no extra cost in the same zone, from €19.99/month.

RED by SFR also includes 35 Go of roaming in its Spécial Voyage 350 Go 5G plan (€19.99/month), valid in Madagascar as across its whole world zone. Orange covers the country through its Pass Évasion (up to 5 Go, around €29, with a discount for 18-26 year-olds) rather than through a plan that already includes it. Bouygues Telecom offers a Pass Monde with 3 Go valid for 30 days, around €30, or shorter Internet Travel Passes depending on trip length.

As always with roaming, it's worth checking the exact terms shown in your carrier's client area just before leaving: data allowances and covered destinations change from year to year, and an old plan doesn't always reflect the 2026 offer.

At Ivato International Airport, near Antananarivo, Telma, Orange Madagascar and Airtel counters are set up in the arrivals area; with your passport in hand for the mandatory line registration, activation takes just a few minutes on the spot. A bare SIM card typically costs between 2,000 and 5,000 Ar (under €1), plus a data bundle sized to your trip.

Telma, the historic operator, remains the go-to choice for anyone planning to drive off the main roads: it's the network that reaches furthest along the RN7 and into rural areas, with a 15 Go bundle around 20,000 Ar (roughly €4) — one of the best value options in the country. Orange Madagascar and Airtel cover towns and main roads well, with smaller bundles (5 Go around 10,000-12,000 Ar, 10 Go around 18,000-22,000 Ar) but coverage that drops off sharply away from paved roads.

To skip the counter queue on stepping off the plane, a tourist eSIM can be activated from an app before boarding. Airalo offers Madagascar plans on the Orange network, around $8 for 5 Go — a decent option for covering the airport-to-rental-office leg and the first few days around the capital. Holafly bets on unlimited data, with plans ranging from about $10 for a single day to over $110 for a month, with a 5-day unlimited eSIM around $21.

This kind of eSIM mainly secures the first days of the trip; nothing stops you switching to a local Telma SIM once out on the RN7, to get rural coverage that neither Airalo nor Holafly — both built on the Orange or Airtel networks — can match once you're outside the towns.

On the RN7, Telma holds an almost continuous signal as far as Fianarantsoa and intermittently on to Ranohira, with frequent gaps on the mountain stretches between the larger towns. The Isalo massif itself, by contrast, is hiked entirely without signal: neither the canyons nor the natural pools get reception, which is no issue with the mandatory local guide but is worth knowing before setting off alone from camp.

Western Madagascar is noticeably more disconnected: the track toward Morondava and the Tsingy de Bemaraha, with its two river crossings on the Tsiribihina and Manambolo, runs through long stretches without any coverage at all, even for Telma. Andringitra National Park, in the southern highlands, sees the same sharp cutoff the moment you leave the access track. In both regions, it's best to have downloaded your offline maps and told your accommodation your expected arrival time before losing signal, rather than counting on reconnecting somewhere along the way.

Rule number one of a Madagascar road trip — never drive after dark, given unlit zebu carts and invisible potholes — makes daytime connectivity all the more valuable: it lets you plan legs precisely enough to arrive before nightfall, rather than discovering a longer-than-expected final stretch once the signal is gone. Download your offline maps systematically before leaving any town, since regaining a connection partway along a track is never guaranteed.

A study by Suzanne McEvoy, Mark Stevenson and co-authors, published in 2005 in the British Medical Journal, compared the phone records of 456 Australian drivers hospitalised after a crash with their phone use in the minutes beforehand: crash risk was roughly four times higher when the phone had been used, hands-free included, with no significant difference between the two (study on Google Scholar: scholar.google.com/scholar?q=McEvoy+Stevenson+2005+role+of+mobile+phones+in+motor+vehicle+crashes+BMJ). One more reason to mount the phone on a dashboard holder with voice guidance, rather than checking it by hand on tracks that already demand full attention.

A few things to check before hitting the road:

Staying connected is just one piece of preparing a Madagascar road trip: the choice between renting with or without a driver, timing the itinerary between the dry season and the rainy season, and the real budget for an island where bank cards only work in towns all deserve just as much thought before setting off.
